FeB17C0.5 Ferro Boron Alloy Lump

Our good quality Ferro Boron Alloy Lump FeB17C0.5 is an iron alloy composed of Boron and iron ,According to carbon content, boro-iron (boron content: 5-25%) can be divided into low carbon (C≤0.05% ~ 0.1%,9% ~ 25%B) and medium carbon (C≤2.5%,4% ~ 19%B). Iron boron is a strong deoxidizer and boron addition agent in steelmaking. The greatest role of boron in steel is that only a very small amount of it can significantly improve the hardenability and replace a large number of alloying elements. In addition, it can also improve mechanical properties, cold deformation properties, welding properties and high temperature properties.

Product Details

Basic information

Ferro Boron is mainly used in steel and cast iron. Used for alloy structural steel, spring steel, low alloy high strength steel, heat resistant steel, stainless steel, etc. Boron can improve toughness and wear resistance in cast iron, and is widely used in the manufacture of automobile, tractor and machine tool. Adding 0.07%B to steel can significantly improve the hardenability of steel. Boron added to stainless steel with 18%Cr and 8%Ni for treatment can cause precipitation hardening, improving high-temperature strength and hardness. Boron in cast iron can affect graphitization, thereby increasing the depth of white cast iron and making it cold, hard and wear-resistant. Adding 0.001% to 0.005% boron to malleable cast iron is beneficial for the formation of ductile iron and the improvement of its distribution. Low-aluminum and low-carbon boroiron is the main raw material for amorphous alloys

Application

Ferro Boron is a critical master alloy in modern steelmaking, primarily valued for its efficiency as a micro-alloying element to enhance hardenability.

The addition of minute quantities of boron (typically 0.0005% to 0.003%) significantly improves a steel's ability to form martensite during heat treatment, allowing manufacturers to achieve high strength while reducing the need for more expensive alloying elements like nickel or chromium . Beyond hardenability, boron improves mechanical properties such as tensile strength and wear resistance through the formation of hard borides and carbides, and it contributes to grain refinement, which enhances both toughness and high-temperature stability .

To deliver this element into molten steel with precision and high recovery, the industry extensively uses boron-containing cored wire. This technology, where crushed ferroboron powder is encapsulated in a steel sheath, protects the boron from oxidation and allows for direct injection into the ladle or tundish via a feeding machine . This method ensures precise control over the final boron content, improves alloy yield, and is essential for producing boron-treated steels like 35MnB or 27MnTiB for automotive and structural applications .

Furthermore, specialized boron-rich cored wires are also utilized in surfacing and hardfacing applications to deposit extremely wear-resistant layers on components exposed to severe abrasion and impact .
